The relative growth rates of zircon crystal faces are recorded by growth zoning, which is recognizable in cathodoluminescence photographs of oriented crystal sections. The kinematics of zircon growth is graphically presented by the slopes of “Grabahnen” between crystal sectors. The relative velocities of advance of crystal faces correlate to the pattern of growth zoning. Widely spaced zoning, interrupted by surfaces of dissolution, on the one hand, and narrowly spaced uninterrupted oscillatory… 
Systematics of internal zircon morphology in major Variscan granitoid types
The internal morphologies of zircon crystals from different types of granitoids (alkaline, calcalkaline and anatectic) are revealed by cathodoluminescence imaging and are described in terms of growth
Factors controlling the development of prism faces in granite zircons: a microprobe study
Based on microprobe work, we present arguments that the size relations of the two common prisms {100} and {110} of accessory granite zircons are strongly influenced by chemical factors. Magmatic
Crystal-plastic deformation of zircon: A defect in the assumption of chemical robustness
Orientation contrast imaging and quantitative electron backscatter diffraction analysis of a zircon collected from an Indian Ocean gabbro reveal intragrain crystallographic misorientations (up to
Distribution of Trace Elements Controlled by Sector and Growth Zonings in Zircon from Feldspathic Pegmatites (Ilmen Mountains, the Southern Urals)
The present study contains the detailed ion microprobe data on trace and rare earth elements distribution in the large zircon crystal about 10 × 6 mm in size with distinct growth and sector zonings
Comparison of Zircon / Apatite Geothermometry Methods and Zircon Typology Data of the Central Anatolian
Zircon typology, proposed by Pupin (1980), is a method based on examination of zircon crystal types in granitic rocks and their statistical evaluation. While providing data for the source of


Zircon saturation revisited: temperature and composition effects in a variety of crustal magma types
Zircon and granite petrology
The typologic study of zircon populations from granitic rocks lead to the proposition of a genetic classification with three main divisions: (1) granites of crustal or mainly crustal origin [(sub)
The Distribution of Solute in Crystals Grown from the Melt. Part I. Theoretical
The incorporation of solute elements into single crystals of germanium grown from the melt is examined in terms of a simple model. The theory takes account of the contribution of solute transport in
Pre-Alpine history of the pennine zone in the Tauern Window, Austria: U-Pb and Rb-Sr geochronology
Zircon ages from major lithologies of the Zentralgneis suggest that much of the Variscan magmatism in the Tauern Window is older than previously suggested. In the southeast Tauern Window a tonalite
On the relations between structure and morphology of crystals. I
An attempt is made by Hartman & Perdok to find relations between crystal structure and crystal morphology on an energy basis. It is concluded that the morphology of a crystal is governed by chains of
L'uranium marqueur de la croissance cristalline : mise en évidence par les traces de fission dans les zircons gemmes d'Espaly (Haute-Loire, France)
Une cartographie precise de l'uranium par fission neutronique induite a ete effectuee sur les zircons gemmes d'Espaly. Il ressort de cette etude que les traces de fission de l'uranium peuvent etre
Une typologie originale du zircon accessoire
Les auteurs presentent une methode d'etude statistique nouvelle des populations de zircon accessoire des roches endogenes ; cette methode est basee sur la typologie des cristaux automorphes et
Mise au point sur la notation des faces du zircon. Élaboration d'une méthode d'indexation rapide des faces des zircons accessoires des roches par utilisation d'abaques
Actuellement les faces du zircon sont tres souvent indexees de deux manieres differentes, suivant que les auteurs decrivent les cristaux macroscopiquement ou etudient le reseau et la structure. Pour
